WebNov 14, 2024 · wedge-and-dash ( uncountable ) ( chemistry) A method of representing the three-dimensional structure of a molecule in which simple lines represent bonds in the plane of the image, wedge-shaped lines represent bonds towards the viewer and dashed lines represent bonds away from the viewer. WebIn all cases, a substituent that was marked by a wedge or a dash in a 2-D drawing will remain that way, but in the chair conformation, the wedge might means axial “up” …

WebJan 23, 2024 · When looking at a problem with wedges and dashes, if the lowest priority atom is not on the dashed line pointing away, the molecule must be rotated. Remember that Wedges indicate coming towards the viewer. Dashes indicate pointing away from the … WebFischer projections were originally developed by German chemist Emil Fischer for work on carbohydrate (sugar) chemistry. It's a way to quickly draw multiple sugars and compare them since it's easy to spot the asymmetric carbons on a Fischer projection. In fact the example which Jay uses in the video is a sugar called glyceraldehyde (both its ...

Let’s start with the E2 mechanism. When the following substituted cyclohexane is treated with sodium ethoxide, an E2 elimination is expected to occur as we have a strong ... WebWedge: A symbol used to indicate the position of a bond or group relative to the plane of the paper or screen. A solid wedge indicates this bond or group is projecting out …
WebUse the solid/dash wedge convention to show three dimensions. Recall that the first step of the reaction above, in which two charged species are formed from a neutral molecule, is much the slower of the two steps, and is therefore rate-determining. WebVideo transcript. - [Voiceover] Let's get some practice drawing chair conformations. One way to do it is to start by drawing two parallel lines that are offset from each other, so let me go ahead and show you what I mean, so here's one line and then here is another line. They're parallel to each other but they're offset a little bit.
WebFor oxidation/reduction in organic chemistry, we're just worried about whether electron density was gained or lost, not full transfer of electrons. ... This would now be a wedge and then a dash, and then this would be a wedge and then a dash. You can see those two hydrogens have added on to the same side. So these two hydrogens or these two ...
